“…Their torsional stiffness is also large. Studies on cellular plates are published in [1][2][3][4][5][6][7], on cellular shells [8]. These cellular structures help designers to solve special problems in the design of welded structures, namely to select between thick unstiffened and thin stiffened structural version.…”

Cellular plates or shells consist of two layers of plates or shells and a grid of stiffeners welded between them. These structures produce large bending and torsional stiffness using relatively small structural height and thicknesses. In the present study the cellular plates and shells are applied for a cantilever column. They are optimized for minimum cost and compared to each other. The column is constructed as a square box cross‐section with cellular plated walls or a circular cylindrical cellular shell. The column is subjected to a compression and a bending force. It is designed for two special constraints: the horizontal deformation at the top and the width of the column are limited. Both versions are applicable, reducing the plate thicknesses, but the cellular shell performance looks better.

“…We have published studies on square cellular plates [5][6][7] with halved rolled I section or welded T stiffeners [8][9][10] with simply supported edges or supported at four corners [11]. We have used cellular plates for box column and box beams [12,13].…”

A cantilever column is loaded by compression and bending, and the horizontal displacement of the column top as well as the outside diameter of the cylindrical shell are limited. The strengthening of the column is performed in the lower part of the column only. Three structural versions of the column are optimized and compared to each other. Firstly, the unstiffened circular shell is optimized, and it is found that the required large thickness is unsuitable for fabrication. Secondly, the stringerstiffened circular shell is optimized. The halved rolled UC section stringers are used only in the lower part of the column; the distance of the interruption of stiffeners is also optimized. It is found that the required shell thickness is unsuitable for fabrication. Thirdly, a new structural version, the cellular shell is used. Cellular shells are constructed from two circular cylindrical shells, and a grid of stiffeners welded between them. They have similar advantages than the cellular plates, namely they can produce a large stiffness with small structural height. Their smooth surface is suitable for corrosion protection, and they are more aesthetic than the stringer-stiffened shells.
